DALLAS (AP) — Medical records provided to The Associated Press show that about 70 staff members at a Dallas hospital were involved in the care of an Ebola patient before his death last week.

The employees at Texas Health Presbyterian Hospital drew Thomas Eric Duncan's blood, put tubes down his throat and wiped up his diarrhea. They analyzed his urine and wiped saliva from his lips, even after he had lost consciousness.

The group included a 26-year-old nurse now being treated for Ebola.

The size of the medical team reflects the hospital's intense effort to save Duncan's life and suggests that many other people could have been exposed to the virus.

The director of the Centers for Disease Control and Prevention says the agency must broaden the pool of people being monitored.
